Dell XPS L501x Battery Life: Good but the 9-Cell Would Be Better

The default battery in the L501x is a 6-cell 56Wh unit, which is more than the paltry 48Wh 6-cell batteries in many laptops but not quite at the 63Wh level seen in others. The combination of Optimus Technology and a reasonable battery means we should see good battery life, but nothing record setting. That's pretty much what we get, with a few oddities.

Battery Life - Idle

Battery Life - Internet

Battery Life - x264 720p

Relative Battery Life

The L501x comes out ahead of many of the 48Wh laptops in the idle, despite having a larger 15.6" LCD, so the slightly higher capacity battery balances things out. Internet battery life is a different story, dropping the L501x down below the N82Jv but still slightly ahead of the ID49C. As bad as that result may look in the chart, it's also still 16% higher than the Toshiba A660D with a 16.7% larger battery, so in that particular test the AMD P920 + HD 4250 matches the i5-460M + GT 420M on a relative basis. In contrast to the Internet result, the x264 playback puts the XPS back ahead of many of the 48Wh batteries.

We had hoped for something a bit more impressive here, but the results aren't bad. It could be that the higher LCD resolution affects some tests negatively (i.e. in the Internet test, you would see more of the test web pages and thus Flash ads further down the page might increase CPU usage). [Update: I retested Internet battery life at 1366x768 and the result didn't change; for some reason the L501x does far worse in that test relative to the other laptops.] HWmonitor also shows the battery at 4% wear despite over 10 cycles, so you might get slightly improved results with a different battery. Ultimately, though, the simple solution to battery life concerns is to spend an extra $40 and get the 9-cell 92Wh battery if you want to run all (or at least most of the) day untethered. There's a compromise in weight with the 9-cell battery, though, and it juts out about an inch below the laptop. I prefer the form factor of the 6-cell battery, but it's always nice to have a choice.

    As always a great review. Just wanted to throw that out there because it amazes me how much people complain about the most ridiculous things in reviews on this site.

    Pc laptop makers still don't get it. (Except HP with Envy line, which is just a knock off of Mac).
    Just like monitor manufacturers. Just make a simple square black border. Don't add curves, or shiny black borders, or ugly angles.

    This thing is horrible to look at.

    Why can't manufacturers make a simple design? I don't care if its a little thicker than a mac, just don't add stupid crap that isn't necessary, put stickers all over it, etc. It's not that hard, and would actually be cheaper to manufacture.
    For instance the thinkpad series, the border of the screen has engraved lines, hooks, odd spacing on one side, different depths. Why?
    I think the timeline x series is close, but still not quite there. It is very close to specs on this except the screen. 3x battery life, better video card, 4.5lbs.

    I think this would be a much better alternative.

    $803 with better specs, better looking, and more custum options.

    We'll have a look at that Clevo B5130M unit in the near future. I can tell you already that it's just as bulky and the speakers sound like crap, and the build quality doesn't look great either. It's got a good 1080p LCD though (very possibly the same one as the L501x).

    As for the curves and other styling, that's ultimately a case of personal opinion. I happen to like the L501x; if I had any serious complaints with it I wouldn't have given it the Gold EC award. Some will like simple, some will like the curves; the angled edges also make it more comfortable to rest your hands on the laptop IMO. Some people think the Alienware M11x/M15x/M17x looks freaking awesome, I find it to be somewhat impractical and am perfectly happy with "average" laptops. I also like the way ThinkPads and Latitudes look and feel -- they're nothing like the L501x, but they're built more solidly.

    I'm a little confused at some of your comments, though... I suppose you're referring to laptops in general, because the L501x is very clean with no stickers to speak of, and I'm not sure what would qualify as "stupid crap" on this laptop.

    Anyway, Clevo's B5130M looks to be a fairly decent laptop and we'll have a full review from Dustin in the not-too-distant future. Stay tuned....

    I was speaking of the sides. I don't mind curves around the screen or body as long as its a uniform look, but the sides just look terrible. At least keep the same color of the palm area.
    The lines should just run even to the back, instead there's some curve and it makes it look like the back flares out.
    I also don't need the dvd, multi reader, cdrw, blu-ray, etc junk on the drive. It just looks so bad.

    Even the Inspiron has cleaner lines, except for some idiot marketing dept that decided glossy black is what people want where their palms rest. Sony has good lines too.

    I also think 1.5" and 6.5 lbs is too much for what you are getting. I am assuming that the speakers are what is taking so much space. Or just bad design.

    " I am assuming that the speakers are what is taking so much space. Or just bad design."

    Or cooling?
    I think Dell may be trying to avoid the overheating issues of XPSs past.

    I like a good looking device as much as the next person but I personally feel Dell made a good call on this one. Half the good looking laptops out there overheat, I would rather have a reliable laptop than one that just looks good.

    The recent Thinkpad series fixed most of the problems you listed, and overall it's a more integrated look. They've got centered screens, no pesky grille things on the screen, etc. However, the hook on the top is still necessary for the Thinklight.

    I think the Latitude E-series are pretty close too. My E6410 is a great looking laptop IMO. Brushed metal lid and all corners.

    As for curves, my opinion is that doing them right is really hard. This laptop clearly doesn't do them well. I personally think that the unibody white Macbook is a really good example of using curves well. It fits really well into the design, and even adds a lot of functionality since the curved edges make a really nice grip.

    It's nice to see a look similar to the older Dell XPS M1530 (which I own), but with more curves added. I am a bit bummed that they kind of tacked on the 1080p LCD without adding a graphics option that can truly handle it. When I looked at Dell's new line-up, I also noticed that the 17" laptop doesn't even have a 1080p option (unless it was recently added) but has the fastest GPU option available.

    * The touchpad belongs in the center of the laptop. No one is using it with their thumbs while also using the keyboard. It should be as large as possible and directly proportional to the aspect ratio of the screen. Also, mouse buttons are dumb.
    * Chiclet keys are the best.
    * Batteries don't need to be super easy to change. If you design your laptop around this principle you will be able to make the laptop smaller while keeping excellent battery life. Maybe make an external battery option for business folks.
    * Lose the optical drive.
    * Only LED screens from now on, please.

    Basically, just make a MBP, minus the optical drive, and knock the $800 apple tax off and everyone on planet earth will purchase your laptop.
  • JarredWalton - Wednesday, November 10, 2010 - link

    1 - Completely disagree on the touchpad buttons. I've used buttonless options and I hated it. Apple seems to have done it better, but I'll keep the buttons thank you.
    2 - I don't think chiclet is best; it's a stylistic thing that looks okay, but if you want a good keyboard try a ThinkPad or a Dell Latitude.
    3 - I agree they don't need to be removable at the flip of a switch for many users, but they also need to be user-replaceable.
    4 - Disagree based on input from quite a few people. I've had more than my share of friends see one of my test laptops without an optical drive and they can't figure out what they're supposed to do. When I tell them to buy an external USB drive or just use the network, they look at me like I'm speaking another language. The masses disagree with you here, and even if Apple goes this route it doesn't make it the right choice.
    5 - Name me one laptop out there that doesn't use LED backlighting... just one! What you need to say is "stop using crappy panels with tons of backlight bleed."

    Pretty much every one of the items in your list is personal opinion, and your opinion is that everything should be a MacBook clone (more or less). I'd like to see a good Windows laptop that incorporates most of the above elements, but by no stretch of the imagination do I think that should be the only way to spec out and build a laptop. There's room for a lot of variety, and while some may not like the L501x styling I think it looks great.
